15388346 ÷ 786 
We want to figure out the number of times 15388346 can be divided by 786.

Step 1:
If we divide 1 by 786, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 786

Let's proceed to step 2:
15 divided by 786 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 786

Going ahead to step 3:
The number 786 fits into 153 0 times, leaving a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 153 after subtracting 0 from 153.
Fetch the next digit (8) from the dividend, attach it to 153 and continue: 1538 / 786

Going ahead to step 4:
If we divide 1538 by 786, we get 1 and a remainder of 752.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 786 from 1538 and we're left with 752.
Bring next digit (8) of the dividend behind the 752 and repeat the process: 7528 / 786

Step 5:
786 can be fit into 7528 9 times, resulting in a remainder of 454.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 7074 from 7528, we get 454.
Include the next digit (3) from the dividend after 454, then repeat: 4543 / 786

Moving on to step 6:
If we divide 4543 by 786, we get 5 and a remainder of 613.
The next digit of our result is 5. 
Result so far: 195.0
If we subtract 3930 from 4543, we get 613.
Take the next digit (4) from the dividend and append it to 613, then repeat: 6134 / 786

Let's proceed to step 7:
786 goes into 6134 7 times with a remainder of 632.
Write down 7 as next digit of the result. 
Result so far: 1957.0
Deduct 5502 from 6134 and we're left with 632.
Fetch the next digit (6) from the dividend, attach it to 632 and continue: 6326 / 786

On to step 8:
786 goes into 6326 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 19578.0
Subtracting 6288 from 6326 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
380 divided by 786 is 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 19578.0
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
786 goes into 3800 4 times with a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 19578.04
Deduct 3144 from 3800 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 11:
786 goes into 6560 8 times with a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 19578.048
Deduct 6288 from 6560 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
The number 786 fits into 2720 3 times, leaving a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 19578.0483
Subtract 2358 from 2720 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 13:
When dividing 3620 by 786, we get 4 with a remainder of 476.
Put 4 as the next digit of the answer. 
Result so far: 19578.04834
Subtract 3144 from 3620 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
The number 786 fits into 4760 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 19578.048346
Subtract 4716 from 4760 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
786 goes into 440 0 times with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 19578.048346
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 16:
4400 divided by 786 is 5 with a remainder of 470.
The next digit of our result is 5. 
Result so far: 19578.04834605
Deduct 3930 from 4400 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final outcome is 19578.04834605, with a leftover of 4.7e-07.
